A surface low pressure system strengthened as it traveled from the Plains on 1/21 to Indiana and Ohio on 1/22 and to the East Coast by 1/23.  Moisture being drawn north ahead and around the low interacted with temperatures in the teens and 20s to produce widespread moderate to heavy snow by the evening of 1/21.  Snowfall rates overnight approached 2 to 3 inches per hour locally, with some embedded thunder.  Snow totals by the morning of 1/22 averaged from 6 to 12 inches.  The start time in the header strip above reflects the time that 6 inch accumulations were reported.  An additional 2 to 4 inches fell across the lakeshore counties and Washington and Waukesha counties during the daytime hours of 1/22, as winds turned north-northeasterly and lake-effect snow showers developed.  Total accumulations ranged from 6 to 16 inches.  Specific totals included 16 inches near Timmerman Field in Milwaukee Co., 15 inches near the Kenosha Airport in Kenosha Co., 14.5 inches in Brookfield (Waukesha Co.), 14 inches in Union Grove (Racine Co.), 13.2 inches in Dodgeville (Iowa Co.), 12 inches in Spring Green (Sauk Co.), 11 inches in Juneau (Dodge Co.), 10.8 inches in Ripon (Fond du Lac Co.), 10.5 inches in Palmyra (Jefferson Co.), 10.5 inches in Mt. Horeb (Dane Co.), 10.2 inches in Genoa City (Walworth Co.), 10.0 inches in Argyle (Lafayette Co.), and 9.1 inches in Elkhart Lake (Sheboygan Co.).  Newspapers reported dozens of vehicle accidents and spin-outs. During the evening of 1/22, two people died (indirect deaths) when their car rear-ended a snowplow truck on I-94 in Wauwatosa (Milwaukee Co.) due to poor visibilities and traction. Two other occupants were injured (indirectly-related).  As the low headed off to the east, strong, sustained, north to northeast winds of 17-26 knots (20 to 30 mph) with gusts to 30 to 35 knots (35 to 40 mph) caused considerable blowing and drifting snow and subsequent near blizzard conditions.
